larly for use in sound deadenlng construe-l tions. The invention isdisclosed in my abandoned application, filed August 11, 1927, Serial No. 212,265 of which the present application is a division and is alsodisclosed in 1929, filed February 25, 1929.

The principal object Aof the invention is to provide an improved furringstrip of economical construction which is adapted toengage andsupportthe metal sheets or tile in the completed installation.

A further object of the invention is to provide furring strips alongcertain forms of which the tlle may be moved to or from a given positionwhereby all of the' tiles can be removed without mutilation, other thanpossibly one or two tiles of each row or tier.

Other objects relate to various features of construction of the furringstrips', as will become ap 'arent from a consideration of the followingspecification and drawings,

wherein: y

Fig. 4 shows a modified form of furring strip in which the legs areformed of strips of metal separate from the back or base member, and

Fig. 5 illustrates an additional modification of the invention.

In Figs. '1 and 2 of the drawings, the furring strip is shown formed ofa single piece of sheet metal havin a back or base portion 10, the sheetmateria being folded back substantially parallel to itself Vandpreferably, although not necessarily, almost into contact with theunderface of the base, then as best shown in the sectional view, Fig.v2. The metal faces. A

In Fig. 4 the construction is similar to that shown in Fig. 1, exceptthat the back memberV 1927, Schuim-818,966. Divided and this applicationined January 85, 1928. Serial No. 849,453.

tudinal ledges .or supports 12 for supporting may be of sheet metalhaving flanges 14-which are provided with ears 15 and are adapted forenga ement with the ledges 12 as shown clearly in ig. 2. The material ofthe furring strip is resilient, whereby the legs can be sprung apartsuiciently to permit the insertion of the flanges 14 of the tile 13 andthus effect the inter-locking with the ledge 12 of the ears 15j, as willbe apparent. Although the upwardl bent ed es o the legs are shown foldedbac fairly c ose to the legs themselves, with `only a small clearancebetween these resilient members, it is evident that the extent to whichsaid yis also bent in a direction nearly at ri ht i parts are vbent isnot Iespecially important as long as they are bent back far enough toinsure a positivel locking `en agement `between saidedges and said ears.lso`a smooth bend at the lower end is preferred, to provide a flaring ortapering inlet at the lower end of the furring strip to facilitate theinsertion of said legs 14. Openings 16 are provided forreceivingfastening means such as screws, nails or toggle bolts by means of whichthe furring strips are secured to the wall or ceiling sur- 17 is formedof a strip separate from the strip of which the legs 18 are formed. Thelegs are provided with anges 19 which are s uitably secured to the back17 by any approved means su'ch as welding, whereby the fabri cated stripis made, an integral unit. v

'In Fi 5 a modified form of the furring strip is s own in which the legsand back are formed of a single piece of resilient Sheet Aas material.In this form of the invention, the free edges of the legs are not foldedupward*- v ly to form thesupporting ledges shown in the other li res,but slots 'or' openin 20 are formed in the legs. 21 to provide edges or'WILl surfaces 22. These ledges 22, like the ledges of the previouslydescribed forms of themvention form horizontal supports for the ears ofe tile, permitting inter-locking enga ement. A lthough I have showncertain features of my improvements for the purpose of ilustratin, itvwill be ap. arent that chan ay be made therein wit out departingfrom thespirit of thel invention as defined inthe j appended claims. .l WhatIclaim is:

1. A furring strip formed of sheet metal comprising a supporting basesection and a, pair of resilient 1e s extending therefrom, convergingtoward t eir free edges and having means for positively securing andsupporting one ormore articles inserted therebetween, by a movementtoward said base section.

2. A furring strip of sheet'metal having a -base member adapted to besecured to ,a support and a pair of-resilient legs integral therewith,said legs extending from said base in a direction `away from saldsupport and con verging toward their free edges and being adapted to b esprung apart for the insertion therebetween of members tobe supportedthereby, each leg having at least one ledge substantially normal to theplane of the leg for eifecting positive engagement with one or more ofsaid members.

3. A furring strip comprising a base adapted to/be secured to a support,a airoflegs extending from said base in a irection away from saidsupport, said legs bein spaced apart along correspondin edges an bearingl against each other along t `eir opposite edges, each leg havingmeansfor supporting one of two articlesinserted between said` legs legs beingresilient and tending normally to exert spring pressure against saidarticles to prevent disengagement of the same from the supportingmeans.,

4.45 4.- A metal furring strip comprising abase section and tworesilient leg Lsections sup ported thereby, each le section having afree articles inserted t said 1,sas174 to a backing strip, vthe leg ofeach section being folded inwardly upon itself to form a double portionresiliently bearing against the other double portion.

v 7.v As an article of manufacture a metal furring strip having alateral portion adapted to be secured to"a plane surface and having twoind/ependentl movable resilient leg members spaced .slig tly apart withledgeA forming means thereon, said ledges forming sitive engaging meansfor articles inserted tween said members ,for resisting stresses exertedon said articles in a direction substan- :Elly parallel with the planeof said memrs. l 8. As 'an article of manufacture, a sheet metalfurringstrip T sha said strip comprising L s aped sections disd incrosssection,

posed back to back and s aced slightly apart at theirbases, the legoeach section being folded inwardly to form a double portion resilientlyportion.
